Risk assessment of two new pesticides based on the intestinal fungal community construction and growth status of predatory insects (<i>Arma custos</i>).

ABSTRACT: This study aims to conduct a comprehensive safety assessment of two novel pesticides-tetraniliprole (SZ) and Metarhizium anisopliae (LJ)-with the goal of providing scientific data to underpin the refinement of current risk assessment frameworks for new pesticides and guiding the optimization of field application strategies. Using the predatory insect A. custos as a model organism, we designed negative control (CK) and concentration-gradient experiment to investigate the effects of these pesticides on the physiological indices and growth performance of A. custos. Additionally, we analyzed their impacts on the structural and functional characteristics of the intestinal fungal community in A. custos, as well as the interaction mechanisms between gut fungi and host
